Digital replicas interact with real systems and mimic changes that occur - as they occur. Digital twin adoption is growing due to the low cost, high storage and compute capacity of IoT and cloud.
Docker App is a new tool we spoke briefly about back at DockerCon US 2018. We’ve been working on `docker-app` to make container applications simpler to share and easier to manage across different teams and between different environments, and we open sourced it so you can already download Docker App from GitHub at https://github.com/docker/app.
In talking to others about problems they’ve experienced sharing and collaborating on the broad area we call “applications” we came to a realisation: it’s a more general problem that others have been working on too. That’s why we’re happy to collaborate with Microsoft on the new Cloud Native Application Bundle (CNAB) specification.
Today’s cloud native applications typically use different technologies, each with their own toolchain. Maybe you’re using ARM templates and Helm charts, or CloudFormation and Compose, or Terraform and Ansible. There is no single solution in the market for defining and packaging these multi-service, multi-format distributed applications.
CNAB is an open source, cloud-agnostic specification for packaging and running distributed applications that aims to solve some of these problems. CNAB unifies the management of multi-service, distributed applications across different toolchains into a single all-in-one packaging format.
The draft specification is available at cnab.io and Continue reading
In the market overview section of the introductory part of data center fabric architectures webinar I made a recommendation to use larger number of fixed-configuration spine switches instead of two chassis-based spines when building a medium-sized leaf-and-spine fabric, and explained the reasoning behind it (increased availability, reduced impact of spine failure).
One of the attendees wondered about the “right” number of spine switches – does it has to be four, or could you have three or five spines. In his words:

(Preprint)
This is a transactions paper with a twist. The transactions we’re talking about are purchases of digital assets. More specifically, the purchase of a file (document, movie, archive of a dataset, …). The property we strongly care about is atomicity: either the seller receives payment and the buyer receives a valid file or neither of these things happen. The buyer and seller don’t trust each other (so e.g., “you send me the payment and then I’ll send you the file” is not an acceptable solution, nor is “you send me the file and then I’ll send you the payment”). This is known as the fair exchange problem.
Fair exchange is a well studied research problem. It has been shown that without further assumptions fair exchange cannot be achieved without a Trusted Third Party (TTP). To circumvent this impossibility, research has studied weaker security models— most notably, the optimistic model in which a TTP is consulted only in case one party deviates from the expected behavior.
In many real-world scenarios, escrow services play the role of the trusted third party. Unfortunately this means you Continue reading

The winner of this year’s Chapterthon was announced this Tuesday, 4 December during InterCommunity 2018.
Chapterthon is a global Internet Society (ISOC) Chapters and Special Interest Groups (SIGs) marathon, where all the Internet Society members can participate by developing a project within a timeline and budget to achieve a common goal. The project winner is selected by the community through online vote.
This year our community worked on the Internet of Things (IoT) – The future is ours to shape.
Every year, the Chapterthon brings enthusiasm and excitement amongst our community. During two and half months, 43 Chapters and Special Interest Groups (SIGs) from across the globe worked alongside to bring awareness on the Internet of Things (IoT) to their communities. They ran over 200 training sessions and workshops, engaging students, entrepreneurs, and local governments. They organized national campaigns, their projects were mentioned in local newspapers, and their message was brought to the most remote places. The Chapters also developed IoT applications that may in the future improve the lives of people in their communities, and amongst some of the projects are improved transport systems, agriculture, energy management, home protection, and healthcare.
The projects that received the highest number Continue reading
